Shopping 

Consumerism, a disease that affects almost the entire population of the first world and yet nobody talks about it. 

It all started with the beginning of the industrial revolution. The peasantry and workers could finally afford to buy goods, and while sales of handicrafts plummeted, the market experienced a huge rise; for the first time, goods were affordable.

However, in the shadows, there was another factor that was to affect society permanently, the decline in the quality of goods due to mass production. Suddenly, a spoon would rust in a matter of days and "wooden" furniture would no longer be damaged by water. 

In this way, companies created a much greater need, the mass purchase of cheap but poor quality goods. In developed countries we became shopping-hungry monsters, and what was once a necessity became a disease.

This is how humanity became infected by consumerism, by shopping for the sake of it; how society became a consumerist monster.
